Ranks

Battlefield 4 features 120 Ranks. All players start out at Rank 0 (Recruit) and will advance in rank by earning experience points (XP) in the online Multiplayer. Rank is strictly a number that shows your dedication to the game, and each Rank has five sub-ranks denoted by Roman numerals and stars.

The current ultimate goal is Rank 120 (Major General).

It seems the only items that are unlocked though ranks in Battlefield 4 are the Battlepacks and Assignments. Weapons are unlocked through Weapon Score, most equipment is unlocked through Kit Score, and Vehicle upgrades are unlocked through Vehicle Score.

Below is a table for all Ranks and Unlocks via Ranks in Battlefield 4. Feel free to add to this, but make sure they're correct. The Score in the table is the overall score, not the amount from level to level.
